Description

Technical Field

[0001] The utility model relates to a device capable of repairing longitudinal tearing of a conveyor belt of a belt conveyor, and belongs to the technical field of belt conveyor maintenance equipment. Background Art

[0002] During the use of the conveyor belt, the conveyor belt often suffers from longitudinal tearing. If it cannot be repaired in time, the tearing will extend to the entire conveyor belt, making the conveyor belt completely scrapped, causing great losses. At present, the commonly used repair methods are cold vulcanization repair of conveyor belts and hot vulcanization repair of conveyor belts. Hot vulcanization repair of conveyor belts requires the use of heating and flattening equipment. When the construction environment is limited, the belt needs to be disassembled before hot vulcanization repair; when cold vulcanization repair of conveyor belts, workers need to stand on the roller conveyor belt to clean, apply glue, paste the repair strip and compact the belt. This situation causes the belt to be in a concave working state instead of a horizontal flat state. During the repair process, it is easy for the glue to flow around, the repair strip to be misplaced and twisted, and the belt below is not in contact with the roller or partially in contact. When the repair strip is compacted, there is no support below, and the degree of compaction cannot be guaranteed. It is easy to crack and damage again. Some conveyor belts are located at a high position, and workers cannot operate on the ground, which affects the repair work. Therefore, it is very necessary to improve the existing conveyor belt modification method. Utility Model Content
